We situate our need for a probabilistic approach which marries data to hypotheses in a principled, actually an algebraicly intelligible, way. Conditional probabilities abound here, ensconced in a 2-decision x 2-state decision frame where states are just hypotheses in decision clothing. We derive rules by which a decision could be supported, but here we are really interested in estimating a probability that a state occurs given the data available. We do so by hand and by R.
